Fix compilation error with plugin_register_shutdown
Compiling collectd-4.10.2 on an OpenSuSE 11.3 system causes the
following error:
snmp.c: In function ‘module_register’:
snmp.c:1620:3: error: passing argument 1 of ‘plugin_register_shutdown’ discards qualifiers from pointer target type
plugin.h:275:5: note: expected ‘char *’ but argument is of type ‘const char *’
Convert plugin_register_shutdown's name argument from 'char *' to
'const char *' in order to match the other plugin_register_*
functions.

dispatch proper values in Python write plugin
Fixes the Python write callback so the appropriate value is dispatched to
Python. Previously, the code only looked at the first element of a data set
to determine which value type (GAUGE, COUNTER, etc) to dispatch. If your data
set consisted of multiple values of different types, then the Python write
plugin was receiving bad values for the elements at position n > 0 whose type
was not the same as that at position 0.

src/plugin.c: Print a more verbose error message if lt_dlopen() fails.
Since the Debian package doesn't depend on the libraries used by the
collectd plugins, some plugins may fail to load. ltdl reports this with
the very confusing error message "file not found". Since the plugin is
in fact available, many users don't realize a dependency is missing and
assume collectd is looking in the wrong directory -- and they are hardly
to blame for this.
This commit introduces a lengthy error message which hopefully points
users into the right direction.

src/utils_threshold.c: Fix creation of percentage notifications.
Joey Hess has reported a problem when creating notifications from
percentage thresholds. Because the (percentage) minimum value is
compared to the (raw) DS value, the following message is possible:
Message: Host XXX, plugin df type df (instance root): Data source
"free" is currently 1773072384.000000. That is above the warning
threshold of nan%.
A new section will handle this case correctly. In the inverted case, the
problem should not exist.

Fix errno thread-safety under AIX
Unlike Linux or Solaris, errno under AIX is not thread-safe by
default.
This patch sets _THREAD_SAFE_ERRNO when AIX is detected in order to
force the thread-safe implementation of errno. Without this, calls
like stat() in the rrdtool plugin fail with errno incorrectly set,
leading to the inability to create previously absent rrd files.
Maybe _THREAD_SAFE should be set instead, to prevent other possible
threads-related problems, but this is enough to scratch my current
itch...
Here is the relevant part of /usr/include/errno.h on AIX:
#if defined(_THREAD_SAFE) || defined(_THREAD_SAFE_ERRNO)
/*
* Per thread errno is provided by the threads provider. Both the extern
* int
* and the per thread value must be maintained by the threads library.
*/
extern int *_Errno( void );
#define errno (*_Errno())
When selecting multiple hosts in collection3's hosts list, and with some
plugins only (the ones that use a specific resource name such as memory
or tcpconns), the resulting graph list will be limited to one single
graph (instead of one per host).
This patch addresses this issue by modifying the name of the hash key
in the group_files_by_plugin_instance function, making it less prone
to name collisions by prefixing it by the host name.

src/utils_tail: Remove newline characters at the end of a line.
The tool is supposed to work line-based, so a) the newline character is
implicit and b) imho, does not belong to the string which is then further
processed.
Also, this allows '$' to match the end of a line when applying a regex to the
line, no matter if the REG_NEWLINE flag has been used when compiling the regex
or not.

src/utils_match.h: Fix a bug preventing derive values from being handled correctly.
Due to the bit-wise check, the value for derive (0x30) matches the check
for gauge (0x10), too. This commit fixes the behavior by assigning other
numeric values to the defines.
curl_json plugin: Use the "number" callback of libyajl.
The "integer" callback only works with "long"s, which are 32bit on
x86 and other 32bit architectures. The "number" callback gets the raw
string for us to parse ourselves – honoring the data source type in the
process.
The "integer" and "double" callbacks have been removed, since they are not
used if the "number" callback is present.

df plugin: Remove the complaint code again.
Calls to the plugin are delayed when an error is returned anyway, so it's
better to have an error message in addition to the "has failed, will suspend"
message generated in src/plugin.c.
